Methyl yellow, which changes from yellow to red around a pH of 4.0
APEX Congo red which changes from red to violet around a pH of 5.0
methyl yellow, (apex: solution with ph balance of 6 and scientist wanting to know when its on 4)
Phenolphthalein, which changes from colorless to purple around a pH of 8.3
Apex
accessibility of body to be measured
my love, you are the moon, don't be jealous of the stars
i'm just kidding phenolphthalein, which changes from colorless to purple around a PH ot 8.3 (apex)
follow me in instamgram itss_kimberlyy

Indicators contain chemicals that will react with certain substances. If that substance is present in your unknown solution, a reaction will occur. If no reaction occurs, then that substance is not present in your solution
Manipulated variables are variables that a scientist deliberately adds in to tweak the outcome of his or her experiment. For instance, a scientist may choose to add certain compounds into a pot of water to see if it may affect the boiling point.
Iodine solution is an efficient indicator for starch. It will go from a light brown colour to a black colour if starch is present and will stay light brown if no starch is present. Hope this Helps!
yes it is
4.0 (APEX)
He or she states the problemThe scientist forms a hypothesis, a possible solution to the problem. The simplest solution is often the best solution.Next, a scientist might want to perform a controlled experiment. A controlled experiment can give a scientist more information about his or hers hypothesis.Results are recorded and analyzed.Using the data the scientist can develop a conclusion.
Curiosity is a part of a scientist's life because only a curious scientist will thrive to answer certain theories
